Here is a different way to look at modifying your PC cooling fan grill with a step by step guide on how we did it!
Tools & Supplies:
1x R/C Truck Rim (83x56mm). We’re using HPI-Racing’s “Hotbodies” Predator Rims
1x 80mm laser cut fan grill. Any design will work, but you must cut 92mm hole in order for rim to sit flush inside)
4x 10/24 x 2″ length machine screws
4x 10/24 Acorn nuts.
4x 1/4″ long aluminum screw sleeves
Dremel or Rotary Tool with 1.5″ reinforced cutting wheel
Hand Clamp.
Rounded side hand file.
Medium grit sandpaper.
Hack saw
GOOP brand Household Glue.
Duplicolor brand “Metalcast” paint (Red, Yellow, Green & Purple)
Plastikote brand “Engine Enamel” Clear coat.

We’ve chosen an 80mm steel “Biohazard” grill, but any design in 80mm will work.
![]()
We’ve clamped down the grill before removing the center portion of the 80mm fan grill.
![]()
Use Rounded side hand file to clean up the edges of the fan grill.
![]()
We’ve chosen the Predator” R/C Truck Rim by HotBodies, but any 83 x 56mm Monster R/C Truck should work with modification.
![]()
We had to cut the front portion of the rim, 1/16″ from the edge.

The R/C Truck rims creates a three dimensional look.

Prep the surface of the 80mm laser cut grill for “Metalcast” paint with Medium grit sandpaper
![]()
We chose Duplicolor brand’s “Metalcast” paint in Purple.

After the Metalcast paint has cured for four hours, apply Plastikote’s Enamel Clear coat and let it cure for 24 hours.

After waiting for the painted grill to cure for 24 hours, apply GOOP brand Household Clear Glue to the Predator” R/C Truck Rim by HotBodies.
![]()
Allow GOOP Glue to cure for 24hrs.

We installed the grill with 80mm Blue LED cooling fan with 10/24 machine screws and acorn nuts, installed as an exhaust. The custom R/C Truck idea turned out awesome! Now we have to decide where we’ll implement the other custom R/C Truck grills in our case!

Shows out of box thinking. Gives me some great ideas.
Keep up the great work guys. I already ordered from you over 160 dollars worth of modding gear for my next rig. Can hardly wait to put my hands on it.
